This study evaluated the correlation between measurements of rib-eye areas of sheep carcasses by traditional methods and those obtained by scanned images. Thirty pictures of the longissimus dorsi muscle of sheep carcasses were drawn on tracing paper and analyzed for muscle area (rib-eye) using four methods: scanned images, which utilizes the software DDA -Determinador Digital de Áreas (Digital Area Determiner); measurements “A” and “B” applied to the equation: (A/2 × B/2) × π; Planimeter method and rib-eye grid method. All […]

The objective of this work was to develop a software to assist the technicians and producers in the determination of the cost of production of milk. The Milk Cost is made up of a plan of calculations encompassing both expenses and incomes. The user can put into a spreadsheet all the expenses and incomes concerning to the milk production system. The software enables the spreadsheet of all the estates and facilities of the production system, aiming the calculations of depreciation […]
